Cerny confirms PSSR2 and FSR4.1 use same neural network

Even Cerny games on PC.

Old news? We already knew that both upscalers use the same neural networks, PSSR2 and FSR4.1 were developed in collaboration between AMD and Sony. That doesn't mean PSSR2 = FSR4.1. They said at the time that PSSR2 was going to be a lighter version of FSR4 optimized for the PS5 Pro's AI cores.

He said so like a year ago, it's not exactly news...

Mark Cerny: FSR 4 for PS5 Pro is the "next evolution of PSSR"

The RDNA 4 upscaler is the first result of AMD/Sony's Project Amethyst collaboration
www.digitalfoundry.net www.digitalfoundry.net

But people here said PS5 Pro couldn't run the same tech of FSR4....

LOL

It's FSR4.1 int8 basically. And that was denied by many people here...

Pro always had power to run it, but it was used for inefficient PSSR1.

Amethyst created core Super Resolution tech. FSR4.1 is FP8 version of it and PSSR2 is int8 version of it.

Sooo what about fsr 5? Aka fsr diamond thats going to be on helix? Is that the same as fsr 4.1 or pssr 2 gonna lag behind or use upgraded fsr 5 and call it pssr 3?

They will jump to FP8 version of tech for sure for PS6. General super resolution tech will reach 2.0 version by then and MS, Sony and AMD will use their variants (with different names).

And this means that AMD has an Int8 version of FSR4.1 ready to go, but refuses to release it for RDNA3. Which has the hardware to accelerate ML in Int8, through its WMMA units. Twats.

FSR 5/Diamond are transformer models for upscaling/framegen/denoising built for RDNA5. Will be pretty much 100% identical between PS6/Xbox Helix/RDNA5 dGPUs regardless of whatever branding each one uses.

Maybe Sony made a deal to have the only INT8 version avaliable, who knows.

PS5 Pro has 2.5x the INT8 TOPS of the the 7900XTX that was the flagship RDNA3 card

How can people expect the same results of a PS5 Pro still baffles me....

If you drop down to the 7800XT then the difference becomes 4x

They don't release it for the same reason PSSR is not available on the base PS5.

It wouldn't work properly

The upscaling never uses all that compute at the same time.
The simple proof is that RDNA3 can run FSR4.0.2 Int8 version well enough, even using the DP4A path and the overhead of Optiscaler.
If AMD released it officially, using the WMMA path it would be significantly faster.

Doesn't change the fact that RDNA3 was never meant to run ML upscalers

And people that bought those cards always said they only cared about raster performance, not "fake pixels"....

Now the very same people complain because they don't get a feature they said they never cared about

See the crazy post above this one

Nonsense. RDNA3 has the hardware to run AI upscalers. It can even run ML programs with RoCm.
AMD could easily put FSR4 Int8 into RDNA3.

Complete rubbish and SMS Ragnarok ML AI texture compression technical paper and the FSR4 leak evidence otherwise.

You do know it is called FSR4.1, yes? The x.1 part denotes a minor upgrade from 4.0, and the leak shows that FSR4 INT8 runs on less than 600GOPs - yes that's correct, not TOPs as in trillions of INT8 OPS per second, but Giga (billions) INT8 OPs per second - via the weakling SteamDeck using it.

For whatever reason, the PS5 - with custom INT8s V_DOT_I32_I8 DP4a type instruction - is being denied FSR4.x support along with lots of equally capable RDNA GPUS.

I hope you are not calculating the cost based on Steam Deck. Steam deck is upscaling from 480p to 720p

Non believers BTFO, especially those of you who said PSSR2 and FSR4.1 have nothing in common.

Just tried FSR Upscaling 4.1 in a few PC games. It's based on the same neural network as the upgraded PSSR we released for PS5 Pro… and it looks stunning!

Just tried? Sorry what? They weren't doing comparisons beforehand?
